Assuming the regulations for 2021 will be changed and finalised in October, is 14 months (November '19 to December '20) enough time for the teams to prepare?

You are making a big assumption if you think that the 2021 regulations will ever be finalised! I'm pretty sure before anything gets agreed for '21 what we have seen so far will be dramatically diluted.
But just for the sake of it let's say it does get through, then 14 months is not a long time for a completely new concept. Normally, if the regulations are staying the same, or with visually minor but aerodynamically major changes like we have had for the 2019 season, research will always be ticking away in the background and some time will be allocated to researching what the changes might do to the current package.
